The present invention relates to a hitch, mediate portions of the braces8 and have and has for one of its prime objects the probearings 10 attheir upper ends for rockably vision of a hitch preferably for use on' atracreceiving a crank shaft 11. This crank shaft tor, and whereby thevehicle or apparatus 11 has a crank portion 12 intermediate its 5 to betowed by the tractor may be readily and ends and at one end has anoperating crank 55 easily coupled therewith. 14 which is provided with adetent structure An additional object is to provide a hitch 15 ofconventional formation for cooperatfor use on a tractor which may bequickly ing withthe notched quadrant 16 on one of and convenientlyadjusted by the operator the fenders 7.

The present embodiment of the invention has been disclosed in detailmerely by way of example since in actual practice it attains thefeatures of advantage enumerated as desirable in the statement of theinvention and the above description.

It will be apparent that changes in the details of construction, and inthe combination and arrangement of the parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. An adjustable tractor hitch of the class described for use with atractor and a drawing tongue; wherein the tractor includes thedifferential housing, a disk, a pair of fenders, and braces extendingfrom the housing to the fenders and wherein the tongue includes a pairof bars projecting forwardly therefrom and having a pair of spacedrollers journaled therebetween; comprising a crankshaft having anoperated crank portion intermediate its ends operating crank at one end,means for journalling the crank shaft above the braces, a draw barattached to the hitch and inclining upwardly and rearwardly therefrom, abracket engaged on the housing and engaged with the upper portion of thedraw bar, a bearing on the operated crank portion, and links dependingfrom the bearing and engaged with the tongue, said draw bar extendingbetween said rollers.

2. An adjustable tractor hitch of the class described for use with atractor and a draw ing tongue; wherein the tractor includes thedifferential housing, a disk, a pair of fenders, and braces extendingfrom the housing to the fenders and wherein the tongue 1ncludes apair ofbars projecting forwardly therefrom and having a pair of spaced rollersjournaled therebetween; comprising a crank shaft having an operatedcrank portion intermediate its operating crank at one end, means forjournalling the crank shaft above the braces, hitch and incliningupwardly and rearwardly therefrom, a bracket engaged on the housing andengaged with the upper portion of the draw bar, a bearing'on theoperated crank portion, and links depending from the bearing and engagedwith the tongue, said draw bar extending between said rollers, means forrockably mounting the crank shaft comprising a pair of brackets risingfrom the braces and bearings at the upper ends thereof.

3. An adjustable tractor hitch of the class described for use with atractor and a drawing tongue; wherein the tractor includes the tween thefenders a draw bar attached to the differential housing, a disk, a pairof fenders, and braces extending from the housing to the fenders andwherein the tongue includes a pair of bars projecting forwardlytherefrom and having a pair of spaced rollers journaled therebetween;comprising a crankshaft having an operated crank portion intern'iediateits operating crank at one end, means for journalling the crank shaftabove the braces, a draw bar attached to the hitch and incliningupwardly and rearwardly therefrom, a bracket engaged on the housing andengaged with the upper portion of the draw bar, a bearing on theoperated crank portion, and links depending from the bearing and engagedwith the tongue, said draw barextending between said rollers, means forrockably mounting the crank shaft comprising a pair of brackets risingfrom the braces and bearings at the upper ends thereof, a detentstructure on the operating crank, and a notched quadrant on one of thefenders associatedwith the detent structure. a

l. A-hitch apparatus for use with tractors and a towing tongue; whereinthe tractor includes a housing for the differential, a hitch, a pair offenders, and braces extending beand the housing; comprising a pair ofbrackets rising from the braces, bearings on the upper ends of thebrackets, a crank shaft journaled in the bearing and including anintermediate operated crank and an end operating crank, a pair of barsfixed to the sides of the tongue and projecting forwardly thereof, andhaving rollers journaled therebetween, a draw bar fixed to the hitch andextending upwardly and inclining rearwardly and extending between therollers, a bracket structure engaged on the casing and engaged with theupper end of the draw bar, a bearing on the operated crank, linksdepending from the last mentioned bearing and engaged with the tongue.

5. A hitchstructure of the class described, comprising a crankshafthaving an intermediate crank portion and an end crank portion, means forrockably mounting the crank shaft on a tractor, a pair of bars forattachment to a tongue'toproject forwardly therefrom, rollers journalledbetween the bars, a draw bar, means, for attaching the draw bar to thehitch of a tractor to extend between the rollers, a bracket structuresuitably mounted on the tractor and adapted to engage with the upper endof the draw bar, means on the bracket for spacing the draw bar toincline upwardlyand rearwardly, and a bearing on the intermediate crankportion and provided with links downwardly for tongue.
